How can I use fields of a mocked struct using mockall?

help

I'm hoping to make a stateful mock object by using mockall to mock a struct with fields I control similar to the following:

struct Counter {
    pub count: u8,
}

mock! {
    pub Counter {}
}

let test = MockCounter::new();
dbg!("Count is {:?}", test.count)

but this fails to compile, complaining that there is no field count on type MockCounter. Is there any way to access custom fields on a mock object or otherwise track custom state? Only other option that comes to mind is static variables, but I would prefer to stay in the scope of mock object definitions for cleanliness and simplicity if possible.

I'm not familiar with the crate, but it seems there's no direct support.

Drat, that's as I feared. Ok, time to switch to fakes :slight_smile:
